On the other hand if "do no evil" means "do no evil as long as it helps our bottom line", then this could very well mean the end of Android's openness. And it doesn't have to be obvious: It could just be that in the future, we'll see cool "Google Android" devices running so-far unreleased OS versions.
"The code will be coming - it's just not quite ready for our partners yet" will be their line.
But the code won't be arriving. Either not until the even newer "Google Android" device is out, or not at all.
We'll see how this will develop.
Personally, I would love to believe Google here because that means that we are going to see awesome pure-google phones which will both be a pleasure to use and well-built hardware-wise, while nobody else will be pissed and will continue to be able to sell their phones - maybe even without paying Microsoft for FAT in the future.
If Google doesn't follow through with their promise, we'll still see awesome devices from them, but the rest of the manufacturers will be stuck with an outdated, possibly not updated any more, version of Android which is a shame because I would really love to see Android on devices that are not pure consumer-phones (like barcode scanners which still run Windows CE or Windows Mobile 6)
The part of Motorola which Google didn't buy, incidentally is a huge producer of these scanners after their acquisition of Symbol Technologies a while back. They continue to produce Windows CE devices to this day.
